Hypervelocity Impacts in a Bingham Solid (think viscous gel rather than solid foam) can set up neat dome patterns in the crater interior depending on the energies involved. (Can also set up bonus waves outside).

Check out entry 8505 in figure 4 in the text.

Maybe whatever Hyperion's target material is (modelling hints that it is volatile rich ice) it can act as a Bingham solid when impacted.
